The specific embodiment
Below in conjunction with Figure of description, embodiment is elaborated to the utility model.
The fender guard structure that the embodiment of the invention provides is as shown in Figure 2, comprises energy absorbent block 4 and door internal decoration plate 5,
Wherein, said energy absorbent block 4 is processed by polypropylene (PP) material of recyclable utilization, and this quality of materials is light, cost is low, and because its composite bending modulus is lower, therefore absorbs lateral energy easily, improves energy-absorbing effect.Being shaped as of said energy absorbent block 4 cooperates the irregularly shaped of door internal decoration plate 5 structures, and the curved surface of said energy absorbent block 4 also is the bending curve of applying door internal decoration plate 5 curved surfaces.Part is provided with a plurality of weld grooves 6 at the edge of said energy absorbent block 4, and said weld groove 6 is structure as a whole with energy absorbent block 4.Preferably, only on two diagonal angles at said energy absorbent block 4 edges, respectively establish a weld groove 6.
As shown in Figure 3, be provided with on the said door internal decoration plate 5 with energy absorbent block on the corresponding welded post 7 in weld groove 6 positions, this welded post 7 is an integrated injection molding with door internal decoration plate 5.Said welded post 7 extend in the weld groove 6, and is fixed together through welding technique, thereby energy absorbent block 4 and door internal decoration plate 5 are linked together, and specifically is connected between said door internal decoration plate 5 and the car door, on the inside face of door internal decoration plate 5.Preferably, said welding technique is the rivet hot welding technique, and weld nugget 8 is between the bottom of the top of said welded post 7 and weld groove 6.Preferably, said weld groove 6 all is positioned at outside the safety zone with welded post 7, to avoid the influence to passenger safety.
Shown in Fig. 4 a, said energy absorbent block 4 adopts cellular structure design, with the energy-absorbing effect of further raising device.Preferably, the forming process of said energy absorbent block 4 is a hot pressing plastics sucking moulding technology, and this technological forming cycle is short, practices thrift preparation cost.Preferably, said cellular structure 9 adopts the thin-wall case design, has further alleviated the quality of energy absorbent block.The shape of the thin-wall case of a plurality of protrusions of said thin-wall case cellular structure 9, size, position and the quantity of arranging all match with the structure of the inside face of said door internal decoration plate 5.Fig. 4 b is the A-A place cross sectional view of Fig. 4 a, wherein, said thin-wall case cellular structure 9 undulates, it simultaneously is the thin-wall case of a plurality of protrusions, another side corresponds to a plurality of grooves.
When car door was collided, the cellular thin-walled housing structure 9 of protrusion can touch energy earlier on the energy absorbent block 4, because energy absorbent block 4 has lower composite bending modulus, cellular thin-walled housing structure 9 deforms, and the buffering part energy reaches the purpose that energy-absorbing is protected.
Visible by the foregoing description, the energy-absorbing fender guard that the utility model provides is owing to adopt the thin-wall case cellular structure design; And adopt thermoplastic polypropylene (PP) material to make the energy absorbent block that has through hot pressing plastics sucking moulding technology; Therefore reduce the quality and the preparation cost of device, improved energy-absorbing effect, and used the rivet hot welding technology that energy absorbent block is fixed on the door internal decoration plate; Improve reliability of fixation, avoided the relevant issues of bringing with glue such as smell.
